NAR Design Unveils 85-Foot Catamaran Concept with Record-Breaking Interior Space

NAR Design, a yacht design and engineering studio based in Pendik, Istanbul, unveiled an 85-foot catamaran concept whose most novel structural claim is also its boldest: an entire deck dedicated exclusively to the owner, a spatial proposition that would be geometrically impossible on a monohull of the same length.

The architecture behind that claim begins with beam. At nearly 11 metres across, the hull is almost double the roughly 6-metre (20-foot) span typical of an 85-foot monohull. That width generates an estimated 250 gross tonnes of enclosed volume, yielding approximately 1,830 square feet of interior space and more than 3,200 square feet of exterior deck area. The owner's deck sits atop a layout that also incorporates a large aft beach club and a plush bow lounge. Rooftop solar panels are specified for hotel-load generation, aligning with the sustainability expectations that now accompany most serious superyacht build programmes.

Two recognisable benchmarks give the volume claims useful context. The Lagoon Seventy 7 measures 23.28 metres with an identical 11-metre beam and a listed displacement of 56.8 tonnes. The Sunreef 80 stretches to approximately 24.4 metres, carries a marginally wider 11.53-metre beam, and displaces a considerably lighter 32.77 tonnes. NAR's concept adds roughly 1.4 metres over the Sunreef 80 and 2.5 metres over the Seventy 7, which accounts for some of the exterior deck gain. Neither benchmark designates a complete deck level as an exclusive owner's zone, making NAR's layout genuinely uncommon at this scale.

That owner's deck, however, raises constraints the renderings do not resolve. At 25.8 metres, reserving an entire level for one party compresses the space available for crew workflow, which on a vessel of this class typically requires separate guest and service corridors running athwartships. The oversized aft beach club similarly competes for stern real estate with the tender garage: at 85 feet, stowing a practical rigid inflatable alongside a jet ski already consumes most available garage volume. Neither confirmed crew routing nor garage dimensions appear in NAR's published concept materials.

On performance, NAR envisions a cruising speed of 16 knots and a maximum above 20 knots, both within standard expectations for this size and type. The platform is described as fully customisable in layout and technical specifications, giving prospective owners latitude to adjust before a build begins.

The timing reflects genuine market momentum. Medium catamarans spanning 15 to 30 metres commanded 51.89% of global catamaran sales in 2024, and the industry overall is projected to grow from $3.81 billion this year to $6.21 billion by 2035. At the superyacht end, sailing catamaran transactions rose from two in 2023 to five in 2024, according to the Monaco Yacht Show Market Report 2025, a trajectory that suggests accelerating conviction rather than a speculative spike.

Any serious buyer converting interest into evaluation should put four questions directly to NAR: confirmed range at 16-knot cruising speed, the intended propulsion configuration, lightship displacement, and a target price band. The owner's deck concept is genuinely novel at this length; those four answers will determine whether it advances from Istanbul renders to a build berth.
